1 When ordering, please specify termination and packaging codes: e.g. LPD4012-564MLC
  Termination: L = Silver-palladium-platinum-glass frit
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
Packaging:

 

C = 7" machine-ready reel
EIA-481 embossed plastic tape 1000 parts per full reel).
B = Less than full reel
In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter C instead.
D = 13" machine-ready reel
EIA-481 embossed plastic tape. Factory order only, not stocked (3500 parts per full reel).
2 Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. When leads are connected in parallel, inductance is the same value. When leads are connected in series, inductance is four times the value
3 DCR is for each winding. When leads are connected in parallel, DCR is half the value. When leads are connected in series, DCR is twice the value.
4 SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value.
5 Isat: DC current, at which the inductance drops the specified amount from its value without current. It is the current flowing in one winding or the sum of the current flowing in both windings.
6 Irms, both windings: Equal current, when applied to each winding simultaneously, that causes a 40°C temperature rise from 25°C ambient. See temperature rise calculation.
7 Irms, one winding: Maximum current, when applied to one winding, that causes a 40°C temperature rise from 25°C ambient. See temperature rise calculation.
8 Ambient temperature range: –40°C to +85°C with Irms current.
+85°C to +125°C with derated current. Derating curve
9 Storage temperature range: Component: –40°C to +125°C
Packaging: –55°C to +80°C
10 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
11 Electrical specifications at 25°C.
See Qualification Standards for complete environmental and test data.
